Hi, ConJan I saw your post in my challenge regarding yours. I took a look at your obfuscation, it is very effective. I managed to solve the first part.
If you want I can post a working serial for it.

You are good, both. But I don't see any solution :) and I don't mean SN (belive you), but something to help with tracing or some deobfuscator will be nice. How tough was it?
What if I obfuscate more code, will it be much harder? What should be added to make tracing harder?

If is anyone interested in this obfuscation and want to improve it and make (of course) a crackme let me know (give some info on how to), because I will not continue in this project.

@BoRoV: thanks!

@ConJan: in response to your message "If is anyone interested in this obfuscation and want to improve it and make (of course) a crackme let me know (give some info on how to), because I will not continue in this project." ... yes, we'd like to see a new crackme with improved obfuscator!
